Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.

    • High Blood Pressure
      • High blood pressure, also known as hypertension, is a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90. There are two causes of high blood pressure, primary and secondary. Primary high blood pressure is much more common that secondary and its basic causes or underlying defects are not always known. It is known that a diet high in salt increases the risk for high blood pressure, as well as high cholesterol. Genetic factors are also a primary cause. Secondary high blood pressure is generally caused by another condition such as renal hypertension, tumors, and other conditions. Treatment for high blood pressure is generally lifestyle changes and if necessary, diet.
    • Anxiety
      • Anxiety is a feeling of apprehension and fear characterized by physical symptoms. Anxiety disorders are serious medical illnesses that affect approximately 19 million American adults.
    • Sinus Infection
      • Sinus infection (sinusitis) signs and symptoms include headache, fever, and facial tenderness, pressure, or pain. Treatments of sinus infections are generally with antibiotics and at times, home remedies.
    • Dehydration
      • Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract. The best way to treat dehydration is to prevent it from occurring.
    • Brain Tumor
      • A brain tumor can be either benign (non cancerous) or malignant (cancerous), primary, or secondary. Causes and risk factors include age, gender, family history, and exposure to chemicals. Symptoms range from headaches, leg and feet numbness to seizures. Treatment is dependant upon the type and location of the brain tumor.
    • Hypothyroidism
      • Hypothyroidism is any state in which thyroid hormone production is below normal. Normally, the rate of thyroid hormone production is controlled by the brain at the pituitary. Hypothyroidism is a very common condition and the symptoms of hypothyroidism are often subtle.
    • MRSA
      • MRSA (methicillin resistant Staphylococcus aureus) bacteria causes skin infections with the following signs and symptoms: cellulitis, abscesses, carbuncles, impetigo, styes, and boils. Normal skin tissue doesn't usually allow MRSA infection to develop. Individuals with depressed immune systems and people with cuts, abrasions, or chronic skin disease are more susceptible to MRSA infection.
    • Chronic Rhinitis and Post-Nasal Drip
      • Allergic rhinitis symptoms include an itchy, runny nose, sneezing, itchy ears, eyes, and throat. Seasonal allergic rhinitis (also called hay fever) is usually caused by pollen in the air. Perennial allergic rhinitis is a type of chronic rhinitis and is a year–round problem, often caused by indoor allergens, such as dust, animal dander, and pollens that may exist at the time. Treatment of chronic rhinitis and post nasal drip are dependant upon the type of rhinitis condition.
    • Menstrual Cramps
      • Menstrual cramps (pain in the belly and pelvic area) are experienced by women as a result of menses. Menstrual cramps are not the same as premenstrual syndrome (PMS). Menstrual cramps are common, and may be accompanied by headache, nausea, vomiting, constipation, or diarrhea. Severity of menstrual cramp pain varies from woman to woman. Treatment includes OTC or prescription pain relief medication.
    • Migraine
      • Migraine is usually periodic attacks of headaches on one or both sides of the head. These may be accompanied by nausea, vomiting, increased sensitivity of the eyes to light (photophobia), increased sensitivity to sound (phonophobia), dizziness, blurred vision, cognitive disturbances, and other symptoms. Treatments for migraine headache include therapies that may or may not involve medications.
    • Stroke
      • A stroke results from impaired oxygen delivery to brain cells via the bloodstream. A stroke is also referred to as a CVA, or cerebrovascular incident. Symptoms of stroke include: sudden numbness or weakness of the face, arm or leg. Sudden confusion, trouble speaking or understanding. Sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, or loss of balance, and/or sudden severe headache with no known cause. A TIA, or transient ischemic attack is a short-lived temporary impairment of the brain caused by loss of blood supply. Stroke is a medical emergency.
    • Lyme Disease
      • Lyme disease is a bacterial illness, which is spread by ticks when they bite the skin. Initially the disease affects the skin causing a reddish rash associated with flu-like symptoms. It takes weeks to months after the initial redness of the skin for its effects to spread throughout the body. Lyme disease can be treated with antibiotics. Lyme disease can be prevented by using tick avoidance techniques.
    • Upper Respiratory Infection
      • An upper respiratory infection is a contagious infection of the structures of the upper respiratory tract, which includes the sinuses, nasal passages, pharynx, and larynx. Common causes of an upper respiratory infection include bacteria and viruses such as rhinoviruses, group A streptococci, influenza, respiratory syncytial, whooping cough, diphtheria, and Epstein-Barre. Examples of symptoms of upper respiratory infection include sneezing, sore throat, cough, fever, and nasal congestion. Treatment of upper respiratory infection are generally with OTC medication and home remedies.
    • Fibromyalgia
      • Fibromyalgia, formerly known as fibrositis, causes chronic pain, stiffness, and tenderness of muscles, tendons, and joints without detectable inflammation. Fibromyalgia patients have an unusually low pain threshold. Symptoms of fibromyalgia include fatigue, abnormal sleep, mental/emotional disturbances, abdominal pain, migraine and tension headaches, and irritable bladder. Treatment of fibromyalgia involves patient education, medication, exercise, and stress reduction.
    • Dengue Fever
      • Dengue fever is contracted from the bite of a striped Aedes aegypti mosquito. Symptoms of dengue include headache, fever, exhaustion, severe joint and muscle pain, rash, and swollen glands. Since dengue is caused by a virus, there is no specific medicine to treat it. Treatment instead focuses on relieving the symptoms.
    • Stress
      • Stress occurs when forces from the outside world impinge on the individual. Stress is a normal part of life. However, over-stress, can be harmful. There is now speculation, as well as some evidence, that points to the abnormal stress responses as being involved in causing various diseases or conditions.
    • Neck Pain
      • Neck pain (cervical pain) may be caused by any number of disorders and diseases. Tenderness is another symptom of neck pain. Though treatment for neck pain really depends upon the cause, treatment typically may involve heat/ice application, traction, physical therapy, cortisone injection, topical anesthetic creams, and muscle relaxants.
    • Temporomandibular Joint Disorder (TMJ)
      • Temporomandibular joint disorder, or TMJ, is a disorder of the temporomandibular joint(s) that causes signs and symptoms including ear pain, bite problems, headaches, dizziness, clicking sounds in the jaw, tinnitus and/or locked jaws. Behaviors or conditions that can lead to TMJ include teeth grinding or clenching, fingernail biting, habitual gum chewing, trauma to the jaw, stress, and occupational hazards. Treatment for TMJ may include heat, ice, a soft diet, antiinflammatory medications, physical therapy, stress management, occlusal therapy, correction of bite abnormalities, and surgery.
    • Norovirus Infection
      • Norovirus infection causes stomach flu, or gastroenteritis. It's a very contagious illness with symptoms that include nausea and vomiting, diarrhea, stomach cramps, fever, headache, chills, and muscle aches. Norovirus infection cannot be treated with antibiotics, so treatment focuses on maintaining proper hydration.
    • Alcoholism
      • Alcoholism is a disease that includes alcohol craving and continued drinking despite repeated alcohol-related problems, such as losing a job or getting into trouble with the law.
    • Common Cold
      • The common cold (viral upper respiratory tract infection) is a contagious illness that may be caused by various viruses. Symptoms include a stuffy nose, headache, cough, sore throat, and maybe a fever. Antibiotics have no effect upon the common cold, and there is no evidence that zinc and vitamin C are effective treatments.
    • Glaucoma
      • Glaucoma is a common eye condition in which the fluid pressure inside the eye rises because of slowed fluid drainage from the eye. If untreated, glaucoma may damage the optic nerve and other parts of the eye, causing the loss of vision or even blindness.
    • Typhoid Fever
      • Typhoid fever is an illness caused by the Salmonella typhi bacteria. The illness is contracted by ingesting the bacteria in contaminated water or food. Symptoms include headaches, fever, diarrhea, lethargy, aches and pains, and poor appetite. Treatment focuses on killing the Salmonella bacteria with antibiotics.
    • Aneurysm (Brain)
      • Brain aneurysm (cerebral aneurysm) is caused by microscopic damage to artery walls, infections of the artery walls, tumors, trauma, drug abuse. Symptoms include headache, numbness of the face, dilated pupils, changes in vision, the "worst headache of your life," or a painful stiff neck. Immediate treatment for a brain aneurysm is crucial for patient survival.
    • Pregnancy Symptoms
      • Pregnancy symptoms vary from woman to woman. There are some symptoms that are more frequent in some women. These symptoms include a missed period, nausea, vomiting, bloating, weight gain, headaches, food cravings, and mood changes.
    • Coxsackie Virus
      • Coxsackie viruses may be divided into two groups. Type A causes hand, foot, and mouth disease and conjunctivitis, while type B causes pleurodynia. Both types sometimes cause meningitis, myocarditis, and pericarditis. There is no specific treatment for this disease.
    • Leptospirosis
      • Leptospirosis is an infectious disease caused by bacteria. The illness progresses in two phases. Symptoms in the first phase include headache, muscle aches, eye pain with bright lights, chills, and fever. Symptoms in the second phase begin after a few days of feeling well and include fever, aches, and a stiff neck. Some people develop meningitis and abdominal pain.
    • Malaria
      • Malaria is an infectious disease transmitted by the bite of an infected Anopheles mosquito. Symptoms of malaria include chills, pain, fever, and sweating. Though mild cases of malaria can be treated with oral medication, severe cases require intravenous drug treatment and fluids.
    • Tension Headache
      • A tension headache is a headache previously thought to be caused by contraction of the muscles in the back of the neck, on the scalp, and sometimes in the jaw. The term tension-type headache is now preferred, reflecting the fact that research has shown that these headaches may not be related to muscle tension.
